In the conditions of the Republic of Belarus there were presented the results of studies of economic and energy efficiency of new forms of liquid nitric fertilizers with additives of micronutrients, biologically active substances and complex fertilizers with chelating forms of micronutrients on growth, development, and formation of grain productivity and quality of spring wheat (Triticum aestivum) of Rassvet variety. Researches were spent in 2006-2008 in field experiences on sod-podsolic sandy loam soil in an industrial site 'Lapenki' UO APK 'Putrishki' in the Grodno district of the Grodno area (Belarus). It is established that influence of liquid nitric fertilizers on the basis of KAS, sated with microcells and growth regulators promotes, increase in productivity of spring wheat at 14,9-23,7 c/hectares, profitability level - on 47-90%, bioenergetic coefficient - on 2,4-3,9 units. The special attention is deserved by a variant N90 KAS with Epin + P55K120 and N90 KAS with Cu3 + Mn1 + Hydrogumate + P55K120N90 KAS with Epin1 + P55K120 and N90 KAS with Cu3 + Mn1 + Hydrogumate + P55K120, where productivity of level of profitability of 85-90% of 56,2-57,4 c/hectares, bioenergetic coefficient - 9,8-9,9 units.
